Possible heating problem

[tlev1987]

I have just finished building my 1st pc and I'm pretty happy with it but there might be an overheating problem with it. I'm confused because the idle cpu temps seem fine but there is such a drastic change when it's under load. I ran prime95 and it got to the low 90'sC! I'm using the stock cooler for intel i-5 2500k. Idle temps are mid 30's C. Is the stock cooler that bad? What would be a decent replacement cooler?

Side note when gaming it seem to top out at 80 C.

Please supply a full parts list.

These temps are according to what software?

Your heat sink is improperly installed or whatever ya using to check it is bonky.....try running OCCT 4.0 CPU test ..... it will load ya CPU, and graph ya temps..... will do ya GPU too.

I was using core temp 1.0 to get my temps.

Parts list:

i-5 2500k cpu

Intel stock coolers are notoriously difficult to secure to the board properly. Check your pins on the back side of the board, to make sure they are properly engaged.

In hopes of increasing your confidence in the answers you've gotten so far, I think it's pretty plain that your cooler is not properly installed. I use Core Temp, and it works. I recommend you get the grapher add-on so you can see changes over time.

I tried real temp 3.60 too and it was running hot under load even after I made sure the pins were pushed in tight. I guess I'll try to re-apply thermal paste or look for a new cooler when I get the time.

to qoute, because I'm lazy tonight

From Arctic silver Ceramique instructions:

If your heatsink has thermal material or a thermal pad on it, the existing material
or pad must be removed prior to applying the new thermal compound. Only the
new thermal compound should be between the heatsink and the metal cap of the
CPU.
NEVER use any petroleum based cleaners (WD-40, and many automotive
degreasers) on the surface of a metal cap or heatsink. The oil, which is
engineered to not evaporate, will fill the microscopic valleys in the metal and
significantly reduce the effectiveness of any subsequently applied thermal
compound.
Thermal pad removal: Most thermal pads are made with paraffin wax that melts
once it gets hot. As it melts, the wax fills the microscopic valleys in the heatsink
and metal cap of the CPU. To minimize permanent contamination of the heatsink
and metal cap, the thermal pad should be removed from the heatsink prior to
turning on the computer. Never use heat or hot water to remove the pad, as the
heat will melt the wax into the heatsink.
Take care not to scratch the surface of the heatsink when removing the pad. A
plastic tool will scrape off the thermal pad without scratching the metal surface.
You can then remove the remnants of the wax with ArctiClean 1 and 2, a xylene
based cleaner (Goof Off and some carburetor cleaners), or high-purity isopropyl
alcohol and a LINT FREE cloth (a lens cleaning cloth or a coffee filter). If you
use Goof Off or another xylene based cleaner always follow up with a cleaning of
high-purity isopropyl alcohol.
Thermal material removal: Remove existing thermal material with ArctiClean 1
and 2, a xylene based cleaner (Goof Off and some carburetor cleaners), or highpurity
isopropyl alcohol and a LINT FREE cloth (a lens cleaning cloth or coffee
filter). If you use Goof Off or another xylene based cleaner always follow up
with a cleaning of high-purity isopropyl alcohol.
Important: Keep the surface free of foreign materials and do NOT touch the
surface after it has been cleaned. A hair, piece of lint, and even dead skin cells
can significantly affect the thermal interface's performance. Oils from you fingers
can adversely affect the performance by preventing the micronized silver or
ceramic fill from directly contacting the metal surfaces. (Fingerprints can be as
thick as 0.005")

Well finally solved my problem. Got the cooler master hyper 212 evo today and installed it. It works great! almost 30c lower than stock intel cooler under load which was a piece of crap. It looked like the pre-applied thermal paste on the intel cooler didn't spread very well too. Thanks everyone for their suggestions. I will stay away from the intel stock push pin coolers in the future to avoid the hassle.
